 # Onomondo SoftSIM for Nordic nRF91 Series
 
 > [!IMPORTANT]
-> This repository is currently supporting nRF Connect SDK v2.5.1 to v2.6.2.
+> This repository is currently transitioning to Zephyr Sysbuild
 >
-> The repository is not yet ported to default sysbuild, introduced in nRF Connect SDK v2.7.0.
+> Please ensure that West is configured accordingly or that you build the project using the --sysbuild argument.
 >
-> To build the samples with nRF Connect SDK v2.7.0, use the build option --no-sysbuild

-> Feel free to contribute to this repository if you have already done the migration to sysbuild.
+> Feel free to raise an issue or contribute to this repository if you experience any issue with the migration to sysbuild.
 
 The Onomondo SoftSIM is an [Open Source](https://github.com/onomondo/onomondo-uicc) C based UICC implementation, allowing new and innovative cellular device designs to see the light of day in the ever-growing landscape of IoT!
